 - **Azure Disk Encryption** helps protect and safeguard your data to meet your organizational security and compliance commitments. ADE encrypts the OS and data disks of Azure virtual machines (VMs) inside your VMs by using the [DM-Crypt](https://wikipedia.org/wiki/Dm-crypt) feature of Linux or the [BitLocker](https://wikipedia.org/wiki/BitLocker) feature of Windows. ADE is integrated with Azure Key Vault to help you control and manage the disk encryption keys and secrets.  For full details, see [Azure Disk Encryption for Linux VMs](./linux/disk-encryption-overview.md) or [Azure Disk Encryption for Windows VMs](./windows/disk-encryption-overview.md).
 
-- **Server-Side Encryption** (also referred to as encryption-at-rest or Azure Storage encryption) automatically encrypts data stored on Azure managed disks (OS and data disks) when persisting on the Storage Clusters.  For full details, see [Server-side encryption of Azure Disk Storage](./disk-encryption.md).
+- **Azure Disk Storage Server-Side Encryption** (also referred to as encryption-at-rest or Azure Storage encryption) automatically encrypts data stored on Azure managed disks (OS and data disks) when persisting on the Storage Clusters. When configured with a Disk Encryption Set (DES), it supports customer-managed keys as well. For full details, see [Server-side encryption of Azure Disk Storage](./disk-encryption.md).
 
 - **Encryption at host** ensures that data stored on the VM host hosting your VM is encrypted at rest and flows encrypted to the Storage clusters. For full details, see [Encryption at host - End-to-end encryption for your VM data](./disk-encryption.md#encryption-at-host---end-to-end-encryption-for-your-vm-data).
